The present disclosure provides a power adapter, which includes a cover and electronic components. The cover includes an upper casing, which is provided with a protruding part on an inner sidewall thereof, and a lower casing, which fits with the upper casing to form an accommodating chamber. The sidewalls of the lower casing and the protruding part are fitted and then connected together, and the electronic components are disposed in the accommodating chamber.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A power adapter, comprising: a cover, comprising: an upper casing, wherein an inner sidewall of the upper casing is provided with a protruding part; and a lower casing, fitting with the upper casing to form an accommodating chamber, wherein a sidewall of the lower casing fits with the protruding part to connect them together, and the sidewall of the lower casing abuts against a lower surface of the protruding part, an upper surface of the protruding part contacts with the accommodating chamber; and electronic components, disposed within the accommodating chamber.
2. The power adapter according to claim 1 , wherein a lower surface of the protruding part is provided with a groove, and a corresponding sidewall of the lower casing is provided with a rib, wherein the groove and the rib are fitted and then connected together.
3. The power adapter according to claim 1 , wherein a lower surface of the protruding part is provided with a rib, and a corresponding sidewall of the lower casing is provided with a groove, wherein the groove and the rib are fitted and then connected together.
4. The power adapter according to claim 1 , wherein the protruding part extends along a horizontal direction of the inner sidewall of the upper casing.
5. The power adapter according to claim 1 , wherein both ends of the protruding part are provided with a bending portion which extends vertically along the inner sidewall of the upper casing.
6. The power adapter according to claim 1 , wherein a distance between the protruding part and a top end of the upper casing is longer than a distance between the protruding part and a bottom end of the upper casing.
7. The power adapter according to claim 1 , wherein the upper surface of the protruding part is provided with one or more reinforcing ribs.
8. The power adapter according to claim 7 , wherein the reinforcing ribs are provided at intervals on the upper surface of the protruding part.
9. The power adapter according to claim 1 , wherein the protruding part protrudes into the accommodating chamber by a length greater than or equal to a thickness of the sidewall of the lower casing.
10. The power adapter according to claim 1 , wherein the cover further comprises a filling layer, which is provided on the inner sidewall of the upper casing between the protruding part and a top end of the upper casing.
11. The power adapter according to claim 10 , wherein the filling layer is a metal layer.
12. The power adapter according to claim 1 , wherein the upper casing is made of plastic material.
13. The power adapter according to claim 1 , wherein the lower casing is made of plastic material.
14. The power adapter according to claim 1 , wherein the sidewall of the lower casing and the protruding part are welded to connect together by ultrasonic wave.
15. The power adapter according to claim 1 , wherein the sidewall of the lower casing and the protruding part are adhered to connect together with glue.
16. The power adapter according to claim 1 , wherein a side surface of the protruding part close to the accommodating chamber contacts with the accommodating chamber.
